Illustration

The following figure shows the wiring diagram of the 140 ARI 030 10 module in a high-interference environment.

Instruction Notes

Use twisted-pair shielded cable in a high-interference environment.
Ground the cable shield close to the module side.
We recommend that you put the magnet ring close to the module side. When using twisted-pair is difficult (especially for 3-wire), use the magnet ring.

Follow the pattern in the table for twisted-pair:

Step	Mode	Description
1	4-wire	ISOURCE+ twisted with ISOURCE- VSENSE+ twisted with VSENSE-
2	3-wire	ISOURCE+/VSENSE+ twisted with ISOURCE- VSENSE+ go alone — or — ISOURCE+/VSENSE+ twisted with VSENSE- ISOURCE+ go alone
3	2-wire	ISOURCE+/VSENSE+ twisted with ISOURCE-/VSENSE-
